Question

I’m upgrading an app from Rails 3.0 to 3.1. We’ve been using Compass and scss.

I’m getting an error when I do both of the following:

• Use a sass-rails helper, like image-path
• Use config.sass.load_paths in application.rb to tell it where to find things like Blueprint.

For example:

config.sass.load_paths << "#{Gem.loaded_specs['compass'].full_gem_path}/frameworks/compass/stylesheets"
config.sass.load_paths << "#{Gem.loaded_specs['compass'].full_gem_path}/frameworks/blueprint/stylesheets"

The error that I get is like:

undefined local variable or method `config' for #<Sass::Script::Functions::EvaluationContext::0x00000105102998>

I have this in my Gemfile:

group :assets do
  gem 'sass-rails',   '~> 3.1.4'
  gem 'coffee-rails', '~> 3.1.1'
  gem 'uglifier',     '>= 1.0.3'
  gem 'compass',      '0.11.5'
end

… which is exactly what is generated by Rails 3.1.1.

What’s wrong here?

Looks like this is solved by using Compass 0.12. I updated my Gemfile to use this:

gem 'compass', '0.12.alpha.1'

This also makes the config.sass.load_paths directives unnecessary.
